If phobias are just learned, why can't people simply 'unlearn' them by thinking rationally?

This is a common misconception. Phobias are not just simple beliefs. The learning process, via classical conditioning, creates a powerful, automatic physiological fear response that bypasses rational thought. Furthermore, the cognitive explanation highlights that phobias are maintained by deep-seated cognitive biases that distort thinking. The avoidance behaviour, explained by operant conditioning, prevents the individual from ever having an experience that could challenge their fear, so the phobia becomes entrenched and resistant to simple rationalisation.

Does the evolutionary explanation mean we are born with a phobia of snakes and spiders?

Not exactly. The theory of biological preparedness does not suggest we are born with fully formed phobias. Instead, it proposes we are born with a genetic 'preparedness' or predisposition to learn these specific fears very quickly and with little exposure. An infant is not terrified of a picture of a snake, but a single negative experience (even a mild one) with a snake is far more likely to result in a lasting phobia than a similar experience with a flower or a car. It's about the speed and ease of learning the fear.

Why doesn't everyone who gets bitten by a dog develop a phobia of dogs?

This is a key limitation of the simple behavioural explanation. Other factors are involved. The cognitive approach suggests an individual's interpretation of the event is crucial; one person might catastrophise the event, while another might not. Social learning also plays a role – seeing others remain calm around dogs can be a protective factor. There may also be genetic predispositions (diathesis-stress model) where some individuals are simply more vulnerable to developing anxiety disorders following a traumatic event than others.
